Hello,
I'm using dovecot & postfix to bring smtp auth to our customers. Normal
mail clients have no problem at all and I'm so satisfied.
However, we're having problems with Microsoft Exchange server clients.
We're using our postfix-dovecot server as smarhost for several Exchange
Servers, and we wish to use TLS + basic authentication for these
outgoing mails.
But it seems that the way Exchange talks to our server, dovecot gets
confused, and password is used instead username for user lookups, so
authentication fails.
Info: auth(default_with_listener): client in: AUTH 5 login
service=smtp resp=bXlfdXNlcm5hbWU= //(resp=my_username)
Info: auth(default_with_listener): client out: CONT 5
VXNlcm5hbWU6 //(Username:)
Info: auth(default_with_listener): client in: CONT 5
bXlfcGFzc3dvcmQ= //(my_password)
Info: auth(default_with_listener): client out: CONT 5
UGFzc3dvcmQ6 //(Password:)
Info: auth(default_with_listener): client in: CONT 5
bXlfcGFzc3dvcmQ= //(my_password)
Info: auth(default_with_listener): sql(my_user): query: SELECT user,
password FROM users WHERE user = 'my_password'
Info: auth(default_with_listener): sql(my_user): unknown user
Info: auth(default_with_listener): client out: FAIL 5
user=my_password
Any clue if there is a way to make it work, either modifiying Exchange
or dovecot settings?
Thank you very much!
Xavier Romero.
